Abstract

The invention provides a measurement method and a measurement system for an earth volume of road engineering. The measurement method for the earth volume of the road engineering comprises the following steps that image control points are distributed in a measurement area range; coordinate values of the distributed image control points are measured; gridding is performed on acquired point cloud data to form a gridding point set array; position relations between points in the point set array and the measurement area range are judged; when point cloud is in or on the boundary of any convex polygon, a volume of a cube corresponding to the convex polygon is calculated; and integral summation is performed on the earth volume corresponding to excavation and filling based on a calculated result of the volume of the cube to obtain the earth volume of the road engineering. According to the method and the system, the maneuverability, the flexibility and the safety are good; flight scanning measurement and imaging can be automatically performed on a surface feature to obtain high-precision point cloud and image data of an earth surface; and measurement for the earth volume of the road engineering is further realized.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping, in particular to a method and system for measuring earthworks in road engineering. Background technique [0002] It is widely used in the inventory work of resource enterprises. At present, most methods such as manual measurement or laser distance measurement are used, which have a large workload, long time, low precision, and consume a lot of manpower and material resources. Every survey project is a physical and mental test for the owners and surveyors. Contents of the invention [0003] In order to solve the above-mentioned shortcomings, the present invention provides a method and system for earthwork measurement of road engineering, which has good maneuverability, flexibility and safety, and can automatically perform flight scanning measurement and imaging of ground objects to obtain ground surface High-precision point cloud and image data, so as to realize the measurement of...
